Isn't cardiopulmonary arrest a heart attack ?
At any rate I find it incredibly difficult to believe this cop intended to kill the man. And I'm not sure how the civil rights violation gets thrown in there except that Floyd was black. Which is the opposite of a color blind justice system. So the main and most likely proper charge is 2nd degree murder aka Manslaughter. He was sentenced to more time for the civil rights thing than the "Murder", which I find ridiculous.
Also I will point out that last year I was on a jury in a criminal trial of a guy who had over .2 BAC and smashed into a car, killing a young couple and their baby, who burned to death. Another juror and myself were the only two not swayed by the slick BS from the defense attorney and wanted convictions for DUI. What we landed on was 3 counts of negligent manslaughter, for which this piece of crap was sentenced to 8 years in prison and which I seriously doubt he does any more than 4.
I also personally know two different guys that straight up murdered people and did less than 12 years.
Now, all that aside, I sure as hell ain't going to sit here trying to defend his culpability when I frankly have no idea what exactly that is. It just seems to me the sentence was excessive and that putting a cop in general population is ridiculous.
